ATTACHMENT FOR COTTON CLEANING MACHINES Filed March 22, 1929 ATTORNEY Patented May 27, 1930 Joann. BRENNEN,'OF ATLANTA, GEORGIA ATTACHMENT FOR COTTON-CLEANIN G MACHINES Application filed March 22, 1929. Serial No. 349,181. v

This invention relates to an attachment for a cotton cleaning machine, the general object of the invention being to provide a rock shaft in the top of the cleaner, with beater forming partsdepending therefrom, with yieldahle means for normally holding the parts in a position with the beater forming parts in a vertical position whereby when the cotton is thrown against said beater parts why the main beater of the machine, the shaft and beater parts will move to a position where the beater parts will be in a diagonal position and then the yieldable means will return the parts to normal position so that the attachment will exert an opening effect on the cotton in addition to that exerted by the main heaters.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to he hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

I11 describing the invention in detail, ref- .erence will be had to the accompanying drawcorresponding parts throughout-the several views, and in which Figure 1 is an elevation of a cleaning ma- 0 chine equipped with this invention.

Figure 2 is a vertical sectional view through a portion of the cleaner casing. I

Figure 3 is a front view, with parts in section.

In these views, the numeral 1 indicates the cleaner casing in which is located the main heaters 2 carried by the shaft8, this shaft being driven in any suitable manner.

In carrying out my invention, I place a second shaft 3 in the top of the casing, this shaft being in alignment with the shaft 3 and having its ends suitably journaled in the ends of the casing and said ends of the shaft project from the casing. A plurality of depending heaters 4 is fastened to the shaft 3 within I the casing and an arm 5 is connected with each outer end ofthe shaft. A spring 6 bears against the lower end of each arm5 and engages a bracket 7 on the exterior part of each end of the casing, these springs acting to hold lng wherein like characters denote like or the parts with the heaters 4 in depending position.

From the foregoing it will be seen that as the cotton is thrown upwardly by the main heaters, the cotton will strike the heaters 41: and thus cause the heaters to rock the shaft 3 against the action of the springs 6 which engage the arms 5 of the shaft so that said springs arecompressed and thus the springs act to return the parts quickly to normal position so that the heaters l are subjected to practically a continuous rocking movement. The auxiliary heaters 4 will exert a material opening effect on the cotton'thrown against them hy'the main heaters so that the opening action of the machine is greatly increased. It isthought from the foregoing description that the advantages and novel features of the invention 'will be readily apparent.

It is tobe understood that changes may be made in the construction and in the combination and arrangement of the several parts, I

provided that such changes fall within the scope of the appended claim.

l/Vhat I claim is A cotton cleaning machine comprising a casing, a shaft rotatably mounted in the lower portion of the casing, heaters fixed for rotation with the shaft, a shaft mounted in the end walls of the casing parallel to and above the first mentioned shaft, arms extending downwardly from the last mentioned shaft at the ends thereof, tension spr ngs connected to the lower ends of the arms and to the corresponding end walls of the casing and yield-.- ahly holding the arms in a vertical position, and beater members fixed at their upper ends to the last mentioned shaft and extending ver-' tically downwardly therefrom and in verti cal planes with respective alternate ones of" the heaters upon the first mentioned shaft.
